Well, yes, I'm no native English speaker. That might be some issue. But now you tell me that a latice is acyclic? Isn't that the fundamental difference between trees and latices that only the latter has loops while the first only ends in leaves from a single root? (I might have sleept in the university courses 40 years ago)

q.

P.S. The (IT) definition of tree in wiki matches mine: https://en.wikipedia.org/wiki/Tree_structure
For lattice it' looks like it's a term primarily used in maths: https://en.wikipedia.org/wiki/Lattice.
So finally to me it looks like mixing it (here) with meshes (what I was thinking of): https://en.wikipedia.org/wiki/Mesh_(disambiguation)

I'm gonna sidestep the Ps and Qs here :)  to say that one thing that EA-as-a-requirements-tool can help you with is to show the cost of change.

If you have a couple thousand requirements in a breakdown structure, you can easily show that while changing the wording in req '1.2.3.4.5.6' is low impact ('.' being a breakdown/trace), making a similar change in requirement '1' actually requires a massive amount of work.

Precisely how you've implemented your tracing (element nesting or connectors) is secondary. Either way it's easy to show that '1' has hundreds of dependents which each needs to be checked and perhaps changed. You don't need to get fancy and get into cost estimates for the different requirements, the dependency structure is quite powerful on its own when visualized -- something Excel doesn't do very well.

So in this way EA can help you manage, not the requirements as such, but more your stakeholders. Which is often the harder job. ;D

My theories are always correct, just apply them to the right reality.

I just read the German Wiki about requirements (it's German in any way in contrast to the English Wiki entry) https://de.wikipedia.org/wiki/Anforderung_(Informatik). It's a good read, if you can read it.
